WebIn this paper, we will find similar results using excircles instead of incircles. When the cevians through a point P interior to a triangle ABC are drawn, many smaller triangles of various sizes are formed. These triangles have three excircles each. In this paper, we only investigate two configurations of six excircles. red hawk logoWeb24 mrt. 2024 · Given a triangle, extend two sides in the direction opposite their common vertex. The circle tangent to these two lines and to the other side of the triangle is called an excircle, or sometimes an escribed circle.
